microbial cell to cell communication

Environmental microbiology is the study of microbial processes in the environment, microbial communities and microbial interactions. This includes: Structure and activities of microbial communities Microbial interactions and interactions with macroorganisms Population biology of microorganisms Microbes and surfaces (adhesion and biofilm formation) Microbial community genetics and evolutionary processes (Global) element cycles and biogeochemical processes Microbial life in extreme and unusual little-explored environments
